DEVICE FOR LOCKING AND OPERATING DREDGlNG-SPUDS.

SPECIFICATION forming part of Letters Patent No. 492,687, dated February28, 1893.

Application filedApril 23, 1892. Serial No. 430,388. (No model.)

To all whom, it mayconccrn:

Be it known that we, FRANK H..KING and GEORGE W. KING, citizens of theUnited States, residing at Marion, in the county of Marion and State ofOhio, have invented certain new and useful Improvements inDevices forLooking and Operating Dredger-Spuds; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to whieh'it appertains tomake and use the same. Our invention relates to an improvement indredging machinery and more particularly to the construction andarrangement of the spuds. for anchoring the dredger in position,-

the object of the in vention being to provide simple and efficient meansfor locking said spuds after they shall have been embedded in the bottomof the stream or other body of water.

A further object is to provide simple and efiicient mechanism foroperating said spuds.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figure 1 is a side elevation of a dredgerwith a portion broken away and showing our improvements applied thereto.Fig. 2 is an end view. Fig. 3 is an enlarged end or front view, showingour improvements, the boom being removed. Figs. 4 and 5 are detail viewsof operating mechanism. Figs. 6 and 7 are detail views of the spud oranchor lock. Fig. 8 is a view in detail of a portion of a spud showingthe peculiar construction of rack teeth.

A, A, represent spuds or anchors adapted to have a Vertical movement insuitable guides formed by vertical timbers a, and cross bars b.

Secured to the inner face of each spud or anchor A, A, is a rack bar 13of suitable length to suit the work for which the dredge is to be used.These rack bars are preferably made of steel and riveted on either sideof the spud. The notches of the rack bars are preferably made slightlyhooking,that is to say, the notches are made slightly larger at thepoints nearest the spuds as shown in Fig.

8 so that the locking devicehereinafter described will have a sure orpositive engagement with the rack bars and thus support the great weightput upon them, without liability of the disengagement of the lockin gdevices.

. Secured to the spud frames or vertical timbers a, are brackets C, eachhaving a horizontal elongated slot c,said brackets serving to assist inguiding the spuds or anchors in their vertical movements.

Mounted in eachpair of brackets O is a rock shaft D, to which aninwardly projecting arm or lever D is secured, said lever being providedwith a counterbalance weight D From the ends of the rock shaft D, armsor links 01 depend and are provided in their lower ends with elongatedslots d. A bar or dog E is mounted at its ends in the elongated slots 0of the brackets'C, and are connected at its ends in the elongated slotsd of the arms or links at. Connected to the inner ends of the arms orlevers D are cords-or ropes e, which extend upwardly and pass overpulleys f located in the upper portion of the framework of themachine,-from whence they extend in wardly and pass over pulleys glocated near the center of the forward portion of the machine. The ropesor cords, after passing over the pulleys gextend downwardly and areprovided at their free lower ends with rings g or other suitable deviceswhereby to manipulate them. When it is desired to anchor the dredger,the cords or ropes e are first pulled to raise the arms or leversd, towithdraw the bars or dogs E out of engagement with the rack bars (withwhich they are held normally in engagement by the weights arms or leversD), and the spuds willthus be permitted to lower until they touch solidground. The boat or dredger is then locked and the look at one side madeto engage the rack'bar ata point above the lower end thereof, and thenby swinging the boom F around toward this spud, the latter will beforced into the ground by the weight of the boom and attached parts. Thespud at the opposite side of the boat or dredger is operated in the samemanner until both spuds find a solid bearing in the bottom of the streamor lake, or are pushed into the ground deep enough to hold the boatsteady during the operation of dredging. At the stern of the boata spudA is located, and is suitably guided by means of a frame A Mounted onthe boat is a frame G, which carries a series of drums 1, 2, 3, 4, onwhich the swinging chain 5, and the hoisting and down-haul chains 6, 7,are wound,motion being imparted to the shaft which carries the drums bymeans of a steam engine H, through the medium of suitable gearing.Located at a point preferably in'advance of and below the frame G, is ashaft I, carrying at one end, a sprocket wheel 1, whereby motion may beimparted to said shaft I, through the medium of a sprocket chain 1 whichchain also passes over a sprocket wheel Foarried by the shaft ofdrums. 1. 2. 3.

Carried by the shaft I is a series of sprocket wheels, 8, 9, 10, and aseries of clutches 11, 12 and 13 is also carried by said shaft, wherebyany one of the sprocket wheels may be thrown into action, as desired.Located in advance of the shaft I, is a series of drums J, J, J eachcarrying a sprocket wheel 14, 15, 16, which sprocket wheels are adaptedto receive motion from the sprocket wheels 8, 9 and 10 through themedium of a series of sprocket chains, 1'7, 18 and 19.

Connected with the drums J, J are chains K, K, which extend forwardly,over suitable pulleys, and are connected at their forward ends, with thelower portions of the spuds A, A, respectively. A chain K is connectedwith the drum J and extends rearwardly, over suitable pulleys andconnected with the lower portion of the rear spud A The clutches ll, 12,13, are connected by means of suitable rods with levers 20 located inthe forward portion of the boat, whereby to operate said clutches. Fromthis construction it will be seen that by manipulating the clutches l1,l2 and 13 and releasing the spud looks as above explained, the spudswill be raised and the boat or dredger thus released or unanchored.

Our improved spud locks and means for operating the same and the spuds,are very simple in construction,can be applied to either harbor orditching dredgers, are easy to manipulate and very effectual in theperformance of their functions.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

2. The combination with a spud and a rack bar carried thereby, ofbrackets carried by the frame work which carries the spud, arock shaftcarried by said brackets, abar connected with said rock shaft andadapted to engage the rack bar and a weighted arm carried by said rockshaft, substantially as set forth.

3. The combination with suitable framework, a spud located therein andadapted to slide, and a rack bar secured to said spud, of bracketssecured to the framework and provided with elongated slots, a rock-shaftmounted in said brackets, an arm carried by said rock-shaft, and a barconnected with said rock shaft and mounted in the elongated slots in thebrackets, said bar being adapted to engage said rack bar, substantiallyas set forth.

4:. The combination with suitable framework, a spud located therein andadapted to slide, and a rack bar secured to said spud, of bracketshaving elongated slots, secured to the framework, a rock shaft mountedin said brackets, an arm or lever carried by said rock shaft, arms orlinks projecting from said rock shaft and provided with elongated slots,and a bar mounted in the elongated slots in the brackets and connectedin the elongated slots in the arms or links secured to the rock shaft,said bar being adapted to engage the rack bar, substantially as setforth.

- 5. The combination with a dredger, of verticallysliding spuds carriedthereby, rack purpose set forth.

6. The combination with a spud, of a rack bar secured thereto, of aweighted lock adapt- .ed to normally engage said rack bar, substantiallyas set forth.

'7. The combination with a spud, of a rack bar, the notches of said rackbar beinglarger at their ends next to the spud, and a lock adapted toengage said notches, substantially as set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
